UC ANR & UC Riverside IPM Study

Excimex has been selected to partner with research teams from the University of California Agriculture & Natural Resources (ANR) & UC Riverside to understand the current status of bed bug infestations and management tactics used in urban and suburban multiple-occupancy housing facilities.

Widespread increases in bed bug infestations can be attributed to several factors:  increased international commerce and travel; growing urban population density; a growing pesticide resistance; changes in indoor pest management tactics; a lack of awareness by the general public.  Low-income, multiple-occupancy residential buildings in urban California are among the locations where chronic infestations of bed bugs are frequently encountered.  These infestations may be the source of “cross contamination” of bed bugs into other locations.  Management in these settings is extremely challenging due to a high rate of tenant turnover, ease of dispersal or “cross contamination”, inadequate resources, communication barriers and housekeeping issues.  Compounding the growing problem is that contracted services for bed bug treatment are often based on a low dollar acquisition, rather than the excellence of service delivery.

Pyrethrins are commonly used pesticides naturally derived from Chrysanthemum flowers.  Potent and toxic. Pyrethroids are their synthetic relatives. 

Pyrethrins are commonly used pesticides naturally derived from Chrysanthemum flowers.  Potent and toxic. Pyrethroids are their synthetic relatives. 

“Traditional” methods of bed bug control are based upon the repeated applications of pyrethroid* insecticides. (*pyrethroids are synthetic chemical insecticides, with properties similar to the natural pyrethrins, found in flowers, such as the chrysanthemum). These pyrethroid products are regulated by Federal and State agencies.  Even though the use of these products produces some beneficial results, there are serious concerns over the increasing presence of such products in our water supplies.  Simple applications of pyrethroid based insecticides may provide some “immediate” return, and quick revenue to the pest control company. However; the actual efficacy is declining rapidly, since bed bug’s resistance to such products has arisen rapidly.  Survivors of such treatments go on to multiply and re-establish infestations.
Frustration on the part of residents, property managers and property owners has resulted in decisions to take bed bug management into their own hands.  The Internet has provided an abundance of “how to” and “home methods”, many of which are highly dangerous.  As a result there has been an increase in pesticide-related poisonings, and deaths.

Integrated Pest Management (IPM) is a combination of common sense and scientific principles based upon:  Education and Awareness;  General knowledge of the pest (behaviors, habits, life cycle); using the least toxic methods; monitoring and adjusting;  follow up.  It is a “new way” of thinking about pest management that values protection of people; property and our planet.  Emphasis is placed upon preparation, lifestyle, deep cleaning, situational awareness and an establishment of acceptable thresholds for action.  The efficacy of IPM has been demonstrated over the past two years in affordable housing situations in the Southern California area by ExCimex.  

The goals of this project are:

  1. Understand the current status of bed bug infestations and management tactics presently being used (The “Traditional” insecticide application method) in California  urban and suburban multiple-occupancy housing systems,
  2. Demonstrate the efficacy and efficiency of bed bug integrated pest management (IPM) strategies and tactics.

Ultimately, a policy for the effective and cost efficient management of bed bugs in urban and suburban multiple-occupancy housing systems will be developed.

ExCimex will conduct the IPM pest management strategies in selected test sites.  The project commenced in April 2014 and will conclude in April 2016.  The results and conclusions will be peer reviewed by some of the most respected academic and pest management professionals in the United States.
